esterification, ester hydrolysispyridine derivatives with bridgesDespite the fact that the famous antimarlarial quinine (1) has been known for 170 years, there is still considerable interest in its chemical and biological properties. Much of the most recent attention is due to the utility of ...
Lipid hydrolysis was also detected by measuring lipase activity with glycerol ester as substrate. Using a photo fragmentation process that breaks an ester bond we demonstrate the system's ability to produce simple lipids (carboxyl acid). The next system on the energy scale is an amide ester....
Epoxidation/hydrolysis: alkene+meta-chloroperoxy benzoic acid; then H_3O^ Enzyme mechanisms: Trypsin and chymotrypsin illustrate how enzymes recognize their specific substrates and catalyze reaction mechanisms. A) What are the catalytic roles of Asp102,...
3,4-bis(4-methylphenyl) thienothiophene, the first example of peri-(3,4) diaryl thienothiophene has been synthesized by a sequence involving preparation of ketene dithioacetal, Dieckmann type cyclization, ester hydrolysis and decarboxylation.doi:10.1080/00397910008087211...

aProposed mechanism for the cyclization of geranylgeranyl diphosphate (GGPP) to the diterpene copalyl diphosphate, an example of terpene synthase-catalysed cyclization initiated by double-bond protonation, rather than by hydrolysis of the diphosphate ester. PP indicates a diphosphate moiety. 개시된 ...
Studies of artificial hydrolytic metalloenzymes: the catalytic carboxyester hydrolysis by new macrocyclic polyamine zinc(II) complexes with a phenolic-pend... The present study also proves that solvolysis of NA ( i.e. water attack on the ester) does exist, but the reaction rate ( k 0 = 1.1...

During a saponification reaction, the ester group reacts with water and base (mostly NaOH) to form carboxylate ions and alcohol. The carboxylate ion is converted to carboxylic acid. Saponification is named after the fact that soap has long been made by the hydrolysis of fats (esters). ...
